Description:
The Microchip Technology Inc. 93XX66A/B/C devices
are 4Kbit low-voltage serial Electrically Erasable
PROMs (EEPROM). Word-selectable devices such as
the 93AA66C, 93LC66C or 93C66C are dependent
upon external logic levels driving the ORG pin to set
word size. For dedicated 8-bit communication, the
93XX66A devices are available, while the 93XX66B
devices provide dedicated 16-bit communication.
Advanced CMOS technology makes these devices
ideal for low-power, nonvolatile memory applications.
The entire 93XX Series is available in standard
packages including 8-lead PDIP and SOIC, and
advanced packaging including 8-lead MSOP, 6-lead
SOT-23, 8-lead 2x3 DFN and 8-lead TSSOP. All
packages are Pb-free (Matte Tin) finish.

    ... FUNCTIONAL DESCRIPTION When the ORG pin is connected nization is selected. When it is connected to ground, the (x8) organization is selected. addresses and write data are clocked into the DI pin on the rising edge of the clock (CLK). The DO pin is normally held in a High-Z state except when reading ...

  • Page 7

    ... Erase The ERASE instruction forces all data bits of the speci- fied address to the logical ‘1’ state brought low following the loading of the last address bit. This falling edge of the CS pin initiates the self-timed program- ming cycle, except on ‘93C’ devices where the rising edge of CLK before the last address bit initiates the write cycle ...

  • Page 8

    ... Erase All (ERAL) The Erase All (ERAL) instruction will erase the entire memory array to the logical ‘1’ state. The ERAL cycle is identical to the erase cycle, except for the different opcode. The ERAL cycle is completely self-timed and commences at the falling edge of the CS, except on ‘ ...

    ... Erase/Write Disable and Enable (EWDS/EWEN) The 93XX66A/B/C powers up in the Erase/Write Disable (EWDS) state. All Programming modes must be preceded by an Erase/Write Enable (EWEN) instruction. Once the EWEN instruction is executed, programming remains enabled until an EWDS instruction is executed or Vcc is removed from the device. ...

    ... For 93AA66A/B/C and 93LC66A/B/C devices, after the last data bit is clocked into DI, the falling edge of CS initiates the self-timed auto-erase and programming cycle. For 93C66A/B/C devices, the self- timed auto-erase and programming cycle is initiated by the rising edge of CLK on the last data bit. ...

    ... For 93AA66A/B/C and 93LC66A/B/C devices, after the last data bit is clocked into DI, the falling edge of CS initiates the self-timed auto-erase and programming cycle. For 93C66A/B/C devices, the self-timed auto- erase and programming cycle is initiated by the rising edge of CLK on the last data bit.
